applying elastomeric coating. should roof be striped first?
CT, near shore. near New Haven , CT.
we get all types weather, below freezing, hot, humid, rain, hail, snow.
1 story addition on a 2 story house.
pitched roof on 2 story drains onto almost flat roof of 1 story.
wood roof with asphalt shingles .
almost flat roof is leaking.
leaks are unbelievable. I have tried everything with new roof, asphalt shingles, flashing, tar, that ice dam mat. still leaks.
I am now looking at an elastomeric coating.
my questions are,
since the roof is leaking, should i strip the roof, then apply the coating. my concern is the water under the shingles will be trapped and cause rotting. plus, i may have some rotted wood.
if i strip the roof, can the coating go on the bare wood, or should i put something down first?
I am looking at coatings for flat roofs and for ponding water, i want overkill.
do you think "elastahyde 770AXP" is a good choice?
I considered "formflex 6000" but i understand that does not resist hail damage.
any advice?
thanks.

Not a roofer but I used to work for an outfit that had a division that did elastomeric roofs. What we did on the warehouse roof was prime the plywood, apply a coat of elastomeric, then lay some type of fiber mat in the wet paint and smooth it all out. 1 more coat of elastomeric was applied when dry. I was very skeptical but I worked there another 5 yrs or so and that roof never leaked.
